Sr2+ is an interfering ion with a selective coefficient of 4.50*10^-5 for a particular Ca2+ ion-selective electrode. When this electrode is placed in a solution that is 3.00*10^-4 M Ca2+ and 7.00*10^-8 M Sr2+ the potential is -0.350 V. What would be the potential if the same Ca2+ solution contained 0.100 M Sr2+? (assume no other charge in ionic srength)
